A method and apparatus for training a receiver on a source are provided. The receiver is an antenna and the source is a broadcast satellite. A first signal sensor receives at least one signal from the source. The first signal sensor may be a first low noise block (LNB) downconverter of the antenna. At least one secondary signal sensor measures a strength of the received signal. The secondary signal sensor comprises four LNB downconverters, wherein each of the four LNB downconverters are located on each of four sides of the first signal sensor. The measured strength of the received signal is used to provide guidance information for training the receiver on the source. When the broadcast satellite moves relative to the antenna, the secondary LNB downconverters detect a variance in the measured strength of the at least one signal and provide guidance information based on the detected variance, thereby reducing the training time for the antenna.
